Why did Mexico distrust the US in 1820s?

There were several reasons why Mexico distrusted the United States in the 1820s.

1. Texas: One of the main issues of contention between Mexico and the United States was the status of Texas. Texas was part of Mexico at the time, but it was also heavily settled by American colonists. The American settlers in Texas were largely autonomous from Mexican authority, and they desired independence. This led to conflict between the Mexican government and the American settlers, culminating in the Texas Revolution of 1835-1836. Mexico viewed the American settlers in Texas as a threat to its sovereignty, as well as a potential ally of the United States in any future conflict between the two countries.

2. Manifest Destiny: The United States was inspired by an idea called Manifest Destiny in the 19th Century, which advocated westward expansion and the eventual possession of the whole North American continent by the United States. This idea put pressure on Mexico, as it suggested that the United States had a right to acquire Mexican territory.

3. Economic Rivalry: Mexico and the United States also competed economically. Mexico was a major exporter of silver and other raw materials, while the United States was an industrial power. This economic competition led to friction between the two countries, as they sought to protect their respective economic interests.

4. Political Differences: Mexico and the United States had different political systems and ideologies. Mexico was a republic, while the United States was a federal republic. Mexico was also more socially conservative than the United States, and it was wary of the United States' more liberal political ideas.
